finish to its desired brightness.

In the days of slow drawing speeds, no other die lubricant was used. However, as modern ticularly objectionable, extremely undesirable.

According to the drawn completely to its ultimate or finished gage and polish its surface but do not effect any reduction. This wire will be found to have an absolutely clean surface, although it will be otherwise much like the usual liquor finished wire.

It is to be noted that the above is contrary to 5 the usual practice. Since the introduction of this process it has undergone no change. The finishing solution has always been applied prior to the drawing, it being taken for granted that this was the best way. The present inventor's inversion of thestep of applying the metallic coating, and his provision of the extra step of burnishing without relying upon the action of the wire drawing die, results in an entirely new and superior product.

Although not previously mentioned, it should be understood that the character of the finishing solution is varied in the usual manner to produce the color desired. That is to say, the proportioning of the tin and copper may be varied in the old manner, whereby the finish may vary heated air, etc., or natural evaporation may be relied upon alone. This drying is necessary because the cleaning of the finishing solution from the wire is usually done with a liquid such as water.

I claim;

A method of producing liquor finished ferrous wire, including drawing wire ultimate gage, then subjecting said wire to the action of a metallic salt solution of such character as to produce a coating of the color desired and subsequently burnishing without any reduction in said gage and drying said wire. a
